Examples of PartitionAccessor

com.linkedin.d2.balancer.util.partitions.PartitionAccessor
This is the accessor for partition properties. It is here because we want to keep partition properties as data storage only and move the logic of manipulating the data to a separate place. To get a PartitionAccessor, one should use {@link PartitionAccessorFactory}

Examples of com.linkedin.d2.balancer.util.partitions.PartitionAccessor

    LoadBalancerStrategy strategy = new TestLoadBalancerStrategy(partitionDescriptions);


    orderedStrategies.add(new LoadBalancerState.SchemeStrategyPair("http", strategy));


    //setup the partition accessor which is used to get partitionId -> keys
    PartitionAccessor accessor = new TestPartitionAccessor();


    URI serviceURI = new URI("d2://" + serviceName);
    SimpleLoadBalancer balancer = new SimpleLoadBalancer(new PartitionedLoadBalancerTestState(
        clusterName, serviceName, path, strategyName, partitionDescriptions, orderedStrategies,
